External truck positioning

1. Feature introduction

Based on Beidou/GPS differential technology, it realizes the accurate positioning of vehicles and machinery and equipment in outdoor open open areas, which is suitable for the precise positioning of external container trucks in port operation and provides temporary supervision for external vehicles in the port

2. Technical indicators

（1）Centimeter-level positioning in outdoor environments
（2）Using RTK technology, in terms of core positioning chip selection, DN-RH-OTV integrates the Beidou third-generation enhanced RTK module, which supports GPS L1, BDS B1, Galileo E1, QZSS L1 four-star joint high-precision positioning, and is the world's first high-precision module that integrates four systems + Beidou third-generation at the same time. In terms of positioning accuracy, DN-RH-OTV supports better than 5cm in outdoor environments, and can provide accurate level, elevation, speed and other information

3. System features

（1）It is composed of a non-contact positioning terminal of a vehicle-mounted foreign card and an automatic sending and receiving charging cabinet of a vehicle-mounted positioning terminal.
（2）The vehicle-mounted positioning equipment is installed on the vehicle, and the real-time position is reported to the vehicle platform system at the beginning of positioning
（3）The vehicle location system displays data such as vehicle driving path and real-time location information through the WEB interface
（4）The vehicle-mounted positioning terminal can send real-time location data to the positioning data management platform through 4G, and the network port communication supports UDP/TCP/HTTP protocol

4. System benefits

（1）The vehicle-mounted sensor adopts a high-strength fuselage design, which has a strong anti-vibration ability, and can adapt to various harsh environments on the dock and mobile machinery
（2）Adopt industrial-grade, suitable for port machinery and seaside environment laser equipment, special brackets and protection devices to ensure the stable operation of the sensor
（3）The system increases the adaptability to the weather and environment (waterproof, dustproof, high and low temperature resistance, antistatic, seismic resistance, anti-electromagnetic interference)
（4）Intelligent processing of laser point cloud, automatic correction, fast contour acquisition, unique anti-collision strategy
